The entrance is to the north of the Card Shack, so just to the right of the Academy.

1/16 - Haunted Overlook

Go left into the crypt.

2/16 - Creepy Crypt

Pick up the key and go back to Eruptor and the locked gate.

3/16 - Peg Leg Landing

A few new bug enemies to fight, the first hit flips them on their back and the second (if they're still on their back) will kill them. You can also jump on them a couple of times instead of attacking.

Defeating them will open a Monster Gate, if you go down the steps to the right of it you can get an XP ball. On the ship is a [Selfie Spot] and some steps to go to the right and out the back. Cross the bone tilting platform to get to a Lock Puzzle.

4/16 - The Belfry Arena

Soul Gem 1/2 - Tidepool

Inside here you have to defeat a bugs and then a group of four of rats wielding mallets before the Soul Gem appears as a reward.

Return to the ship where Eruptor is waiting and use the bounce pad near the stairs to get up to the ship's wheel. When you walk down to the lower area there's an optional couple of waves of rats to attack, defeating them will get you an [Imaginite Chest].

5/16 - Submarine Spinner Spans

Wait for the submarine to rotate around so that the doorway is on the top, it'll open to let you inside.

6/16 - Upper Submarine Interior

Treasure Chest 1/3

Blast through the crates to find the Treasure Chest at the back next to the ladder out.

Go down to where Eruptor is waiting and wait for the second submarine to turn around so you can get inside it too.

7/16 - Lower Submarine Interior

Soul Gem 2/2 - Quickshot

At the end of this one is a Soul Gem.

Cross over the submarine and push the green eel jar off to the left. You can arrange the jars so that you can get up onto the platform to the left but it just gets you a few more coins so it's nothing to worry about if you just immediately push the jars to the right.

After plugging them in go back around and over the submarine again, to the right of where the first jar was is the Frosting Cannon.

8/16 - Frosting Cannon Terrace

For the first one you just have to shoot the transparent outlines of the icing around the edge of the bottom layer of cake. Ride the rail to the second cannon.

The second cannon adds enemies to the cake, make sure to shoot them as soon as you see them as they'll start destroying the icing that's already been placed. Once they stop appearing you can finish off the empty spots.

And the third one is the same as the second with the top layer added into the mix too. There's a [Selfie Spot] to the right if you want to snap a pic of the finished product. Otherwise ride another challengeless rail out of here.

9/16 - Galaxy Arena

Time to be introduced to the Riff Rat, a larger rat enemy that does close range melee attacks and sometimes leaps at you. Another new type of enemy will be part of this fight, rats hiding in trash cans throwing lumps of cheese that sit and continue to damage for quite a while. You can only attack them when they pop out. These two enemies are introduced together because the larger rats form from the hammer rats if they eat a piece of that rotting cheese, if you can hit the cheese sitting on the floor before a hammer rat can eat it you'll save yourself a lot of trouble. Oh and you can press the big red button in the middle every so often to emit a shockwave that stuns enemies and does a little bit of damage.

After defeating them all you'll get an [Imaginite Chest] and a lever will become active. Pull the lever to raise the floor.

Egg Rescue

To the left of the lever.

Over to the right is a doorway you can go into.

10/16 - Space Lab Storage

Battle Gong

The only thing in here is the Battle Gong. This fight is 38 enemies made up of bugs, rats with hammers, and trash cans. Nothing that can really corner you in this small arena for the [Imaginite Chest].

Go back out and get onto the ferris wheel as it turns around, wait for it to move twice to get off on a ramp towards Eruptor.

11/16 - Cosmic Crane

Defeat a few bugs and a couple of rats to get the lever active, but don't use it yet.

Treasure Chest 2/3

Walk up the crane before moving it as there's a Treasure Chest at the top.

Go back down the crane to pull the lever.

Legendary Selfie Frame - Quickshot

Climb up the crane again as now a Legendary Selfie Frame is at the top in this new position.

Jump off the end and get over the tilting platform that is attached to the crane to get to an area with a new battery puzzle. To get behind the battery so you can push it you need to first push the front block so that it's directly in front of the battery. Then push the left block back twice, push the right block forwards three times and then the first block to the left so that you can now push the battery into place.

If you jump down to the area directly below you can get an [Imaginite Chest] if you complete the Snail Challenge.

Bounce back up and pull the lever on the right of the battery to rotate a tilting platform made up of train tracks.

12/16 - Winterland Adventure

Around the corner is Eruptor again, smash the barrier next to him and jump over the rolling log to reach an area with laods of falling rocks. For a Trophy/Achievement you might want to spend some time attacking the rocks as they fall. Otherwise just avoid them and continue on past an XP ball to an optional game of [Creation Clash] with Tessa.

As you get over the next log you'll see a Treasure Chest being sealed away, you'll get that further on so just carry on over another log and into an arena.

13/16 - Lower Ridge Arena

You'll be attacked by a bunch of rats but not all that many, defeating them all will get you an [Imaginite Chest] and lower a ramp into position. If you fall down into the area beneath the rotating cog you can find a few more enemies and a [Selfie Spot] but it's really just a way of showing you that there's stuff beneath the platforms.

Bounce back up if you went down, cross the cog and go around the corner.

Treasure Chest 3/3

Don't jump down to the area you can see below straight away, instead walk onto the wooden plank section and push the battery jar off. Now jump down and push the two batteries into place to get the Treasure Chest that you saw get locked up earlier.

Bounce back up and cross the two cogs.

14/16 - Upper Ridge Arena

This arena has a button in the middle you can press every so often, use it as much as you like to get rid of the bugs that attack. Defeating all the bugs will get you an [Imaginite Chest] and a ramp out of here.

Before you use the lever on the elevator make sure to jump down to the area below where there's a Lock Puzzle on a door.

To get the [Imaginite Chest] from joining the shards up you can go: Left, Up, Right, Down, Left, Up, Left. Then to get to the end from there go: Right, Down, Right, Up, Left.

15/16 - Engine Room Challenge

There's a bunch of enemies to defeat in here but nothing to collect so turn around and bounce back up to the lever.

Go to the left at the top, past an XP ball and across some rotating tilting tracks.

Troll Radio

The Troll Radio here has Jazz Music and Party Effects.

Pick up the key here. Return to the locked gate by the elevator and continue around to the top of the level.

16/16 - Summit Arena

Before you get to fight the Doomlander you must first defeat a few regular enemies. Once those few are gone it's time for the Quickshot Doomlander. His first attack is rapid-fire but very slow to turn so you should be able to get to his sides or behind him to attack without taking any damage (he tends to run off to stand by the edges).

The new attack that he gains is a long charged single shot but it will bounce on the laser walls so you've got to keep an eye on where it's going. Other than that it's the same as the first part, get to the side of his main attack to safely hit him.

And for the final part he'll get an energy blast attack, you can see him point his guns at the floor when he charges this one up. Jump over it and continue attacking him as before.
